Description

Die vorliegende Erfindung betrifft eine Einrichtung zur Bereitstellung von fliessfähigen Medien, insbesondere von flüssigen oder pastösen Massen, die aseptisch verpackt in einem vollständig geschlossenen Behältnis resp. Schlauchbeutel anliegen, umfassend einen Ausgussstutzen mit einem Flansch, der, auf dem Schlauchbeutel befestigt ist, wobei der Ausgussstutzen in einer Mantelwand ein Innengewinde aufweist sowie einen rohrförmigen Adapter mit einem zum Innengewinde des Ausgussstutzens passendes Aussengewinde an einem Einlassende, und einem konischen, verjüngenden Schlauchaufsatz an seinem Auslassende und einen dazwischen angeordneten Dichtkragen, und dass das -in den Ausgussstutzen einschraubbares Ende des Adapters mit einem das Behältnis bzw. den Schlauchbeutel öffnenden Mittel versehen istThe present invention relates to a device for providing flowable media, in particular of liquid or pasty masses, the aseptically packed in a completely closed container resp. Abutting tubular bag, comprising a spout with a flange which is fixed on the tubular bag, wherein the spout in an outer wall has an internal thread and a tubular adapter with an internal thread of the spout suitable external thread at an inlet end, and a conical, tapered hose attachment on its outlet end and a sealing collar arranged therebetween, and that the end of the adapter, which can be screwed into the spout, is provided with a means opening the container or tubular bag

Es ist seit langem bekannt, aseptisch, flüssige oder pastöse Massen in geschlossenen Behältnissen, insbesondere in Schlauchbeutel abzupacken. Um diese zu öffnen muss das Behältnis bzw. der Schlauchbeutel aufgeschnitten oder aufgestochen werden. Entsprechend sind Verschlüsse bekannt, die hierzu besonders geeignet sind, wie dies beispielsweise die WO 95/05996 zeigt. Hier ist auf dem Behältnis ein Ausgussstutzen mit Flansch befestigt, wobei dieser Ausgussstutzen ein Innengewinde aufweist in dem ein Durchstosser mit Aussengewinde eingeschraubt ist und an seinem untersten Rand mehrere Schneidzähne bzw. Perforierzähne aufweist. Auf dem Ausgussstutzen ist eine Schraubkappe angeordnet, die beim erstmaligen Aufschrauben den Durchstosser nach unten bewegt und dabei das Behältnis öffnet. Solche Verschlüsse sind insbesondere in der Getränkeindustrie sehr verbreitet. Diese Behältnisse sind relativ rigide und zum Öffnen wird entsprechend eine relativ hohe Kraft benötigt.It has long been known to pack aseptic, liquid or pasty masses in closed containers, especially in tubular bags. In order to open these, the container or the tubular bag must be cut open or pierced. Accordingly, closures are known which are particularly suitable for this, as for example the WO 95/05996 shows. Here, a spout with flange is mounted on the container, said spout has an internal thread in which a piercer is screwed with external thread and has at its lowest edge a plurality of cutting teeth or perforating teeth. On the spout is a screw cap is arranged, which moves the first time when screwing the piercer down and thereby opens the container. Such closures are particularly common in the beverage industry. These containers are relatively rigid and to open a relatively high force is required accordingly.

Schlauchbeutel mit aseptisch gefüllten Flüssigkeiten insbesondere mit Salzlösung sind insbesondere in der Medizinaltechnik häufig angewendet, wobei diese Schlauchbeutel aus reinem Kunststoff sind und entsprechend flexibel und sich entsprechend auch wesentlich leichter öffnen lassen. Diese Schlauchbeutel sind für relativ kleine Mengen in der Grössenordung von 300 ml bis 1000 ml. So zeigt beispielsweise die US 4257535 eine Einrichtung auf zur Bereitstellung von fliessfähigen Medien, die aseptisch abgepackt sind und einen Ausgussstutzen mit einem Flansch aufweisen. In diesen Ausgussstutzen wird ein becherförmiger Zapfen eingestossen, der zentrisch einem beidseitig offenen Führungsrohrabschnitt aufweist in den ein Adapter eingesteckt werden kann. Der Adapter besitzt als öffnendes Mittel einen spitz zulaufend gestalteten Zapfen der in den Führungsrohrabschnitt eingeschoben werden kann und die Folie des Schlauchbeutels durchstechen kann. Die entsprechend sich bildende Öffnung ist relativ kein und der anliegende Druck im Schlauchbeutel relativ gering. Sogar wenn beim Einstechen der Schlauchbeutel leicht komprimiert wird, baut sich nur ein relativ geringer erhöhter statischer Druck auf. Entsprechend sind die hierbei auftretenden Dichtungsprobleme relativ gering. Eine relativ ähnliche Lösung weist auch die US Patentanmeldung 2008/0029540 auf. Hier ist der durchstechende Adapter zusätzlich mit Perforier- und/oder Schneidzähnen versehen. Auch hier ist die Dichtungsproblematik kaum relevant. Zudem ist diese Lösung nicht für aseptisch geschlossene Behältnisse konzipiert, sondern auf dem Ausgussstutzen ist ein stopfenartiger Deckel aufgesetzt, der wiederum eine becherförmige Aufnahme hat, der jedoch zum Behältnis hin mittels einer Membran geschlossen ist. Der Adapter, der als Durchstosser konzipiert ist, durchstösst die Membran des Stopfens.Tubular bags with aseptically filled liquids, in particular with saline solution, are frequently used, in particular in the field of medical technology, these tubular bags being made of pure plastic and correspondingly flexible and correspondingly also much easier to open. These tubular bags are for relatively small amounts in the order of 300 ml to 1000 ml. Thus, for example, the US 4257535 means for providing flowable media which are aseptically packaged and have a spout with a flange. In this spout, a cup-shaped pin is inserted, which has centrally a guide tube section open on both sides into which an adapter is inserted can be. The adapter has as an opening means a tapered shaped pin which can be inserted into the guide tube section and can puncture the film of the tubular bag. The correspondingly forming opening is relatively no and the applied pressure in the tubular bag is relatively low. Even if slightly compressed during insertion of the tubular bag, only a relatively small increased static pressure builds up. Accordingly, the sealing problems occurring here are relatively low. A relatively similar solution also points out the US Patent Application 2008/0029540 on. Here, the piercing adapter is additionally provided with perforating and / or cutting teeth. Again, the sealing problem is hardly relevant. In addition, this solution is not designed for aseptic closed containers, but on the spout is a plug-like lid placed, which in turn has a cup-shaped receptacle, which is closed to the container by means of a membrane. The adapter, which is designed as a piercer, pierces the membrane of the plug.

Dasselbe Konzept zeigt auch die JP 56048965 A .The same concept also shows the JP 56048965 A ,

Auch die GB 2154991 zeigt eine Einrichtung zur Bereitstellung von fliessfähigen Medien, die aseptisch verpackt in einem vollständig geschlossenen Behältnis bzw. in einem Schlauchbeutel anliegen. Das hier gezeigte Konzept entspricht der zuvor beschriebenen Lösung weitgehend, doch ist hier auf dem Ausgussstutzen mittels eines Bajonettverschlusses praktisch ein Führungszylinder angeformt, indem ein Injektionskolben anschliesst mittels dem das aseptisch geschlossene Behältnis ausgestochen werden kann und das besondere ist hier, dass dieser Perphorierkolben im Auslass ein Rückschlagventil aufweist, daher das Behältnis mit Unterdruck entleert wird und mittels dem Ventil sichergestellt wird, dass kein Rückfluss stattfindet. Schliesslich ist aus der JP 58037805 U eine Einrichtung zur Bereitstellung von fliessfähigen Medien gemäss dem Oberbegriff des Patentanspruches bekannt.Also the GB 2154991 shows a device for providing flowable media, which lie aseptically packed in a completely closed container or in a tubular bag. The concept shown here corresponds the solution described above largely, but here on the spout by means of a bayonet closure practically formed a guide cylinder by an injection piston connects by means of which the aseptically closed container can be ausgeochen out and the special here is that this Perphorierkolben in the outlet has a check valve, therefore the With vacuum, the container is emptied and the valve ensures that no backflow takes place. Finally is from the JP 58037805 U a device for providing flowable media according to the preamble of claim known.

Es ist nunmehr die Aufgabe der vorliegenden Erfindung eine Einrichtung der eingangs genannten Art für Behältnisse die für grosse Volumen geeignet sind zu schaffen, was einerseits die Problematik mit sich bringt, dass höhere Drucke anliegen als bei Schlauchbeuteln für Infusionen, die entsprechend auch aus dickeren Folien gefertigt werden und bei denen beim Öffnen entsprechend höhere Kräfte erforderlich sind, die auch zu einem erhöhten Innendruck führen. Dies wiederum bedingt eine Lösung, bei der eine verbesserte Dichtung zwischen dem eindringenden Adapter und dem Ausgussstutzen zu erfolgen hat.It is now the object of the present invention to provide a device of the type mentioned for containers which are suitable for large volumes, which on the one hand brings with it the problem that higher pressures apply than in tubular bags for infusions, which are also made of thicker films accordingly be and in which correspondingly higher forces are required when opening, which also lead to an increased internal pressure. This in turn requires a solution in which an improved seal between the penetrating adapter and the spout has to be made.

Diese Aufgabe löst die eingangs erwähnte Einrichtung dadurch, dass der Ausgussstutzen im oberen Bereich eine zylindrische Wand aufweist, die oberhalb des Flansches in einen doppelwandigen Bereich übergeht, mit einem konisch nach aussen verlaufenden Stützwandbereich und einer konzentrischen dazu konisch nach innen gerichteten, elastischen, dünnwandigen, umlaufenden Dichtschürze.This object is achieved by the device mentioned above in that the spout has in the upper part of a cylindrical wall, above the flange in a double-walled area merges, with a conically outwardly extending support wall area and a concentric conically inwardly directed, elastic, thin-walled, circumferential sealing skirt.

Weitere vorteilhafte Ausgestaltungsformen des Erfindungsgegenstandes gehen aus den abhängigen Patentansprüchen hervor und deren Bedeutung und Wirkungsweise werden in der nachfolgenden Beschreibung mit Bezug auf die anliegenden Zeichnungen erläutert.Further advantageous embodiments of the subject invention will become apparent from the dependent claims and their meaning and effect will be explained in the following description with reference to the accompanying drawings.

In der Figur 1 ist die Einrichtung, die insgesamt mit 1 bezeichnet ist, in einer perspektivischen Explosionszeichnung dargestellt. Die Einrichtung besteht aus zwei separaten Bestandteilen, nämlich einerseits einem Ausgussstutzen 2 und andererseits einem darin einschraubbaren Adapter 3. Der Ausgussstutzen 2 ist auf einem hier teilweise sichtbaren und vereinfacht dargestellten Behältniss 4 angebracht. Das Behältnis 4 besteht bevorzugterweise aus einem Schlauchbeutel 4, indem flüssige oder pastöse Massen vollständig geschlossen, aseptisch verpackt anliegen. Beim hier vereinfacht dargestellten Schlauchbeutel 4 handelt es sich um einen sogenannten kissenförmigen Schlauchbeutel. Solche Schlauchbeutel werden industriell beziehungsweise gewerblich eingesetzt um flüssige oder pastöse Medien zu transportieren und diese werden daraus meist über ein Pumpsystem dosiert entnommen. Selbstverständlich ist die Einrichtung 1 auch für andere Gestaltungsformen eines Schlauchbeutels geeignet. Zwar ist die erfindungsgemässe Vorrichtung durchaus auch anbringbar auf quaderförmige Behältnisse aus laminiertem Kartonmaterial, doch ist ein solches Behältnis relativ rigide und entsprechend entstehen auch wesentlich geringere Drücke, so dass das entsprechende Dichtungsproblem, welches hier gelöst wird, nicht die gleiche Relevanz hat.In the FIG. 1 the device, which is designated overall by 1, shown in a perspective exploded view. The device consists of two separate components, namely on the one hand a spout 2 and on the other hand, a screwed therein adapter 3. The spout 2 is mounted on a partially visible here and shown in simplified container 4. The container 4 is preferably made of a tubular bag 4 by liquid or pasty masses completely closed, abut aseptically packed. The tubular bag 4 shown here in simplified form is a so-called pillow-shaped tubular bag. Such tubular bags are used industrially or commercially to transport liquid or pasty media and these are usually taken dosed by a pumping system. Of course, the device 1 is also suitable for other design forms of a tubular bag. Although the device according to the invention may well be applied to parallelepipedic containers of laminated cardboard material, such a container is relatively rigid and correspondingly, much lower pressures are produced so that the corresponding sealing problem which is solved here does not have the same relevance.

Mit Bezug auf die Figuren 1, 2 und 4 wird nun der Ausgussstutzen im Detail beschreiben. Dieser weist eine zylindrische Mantelwand auf, die den eigentlichen Ausguss bildet und indem ein Innengewinde 21 angeordnet ist. Zur Erhöhung der Griffigkeit ist die zylindrische Mantelwand auf der Aussenseite mit einer Rippung versehen. Am unteren Ende schliesst an der zylindrischen Mantelwand ein konisch nach aussen verlaufender Stützwandbereich 24 an, der dann in den eigentlichen endständigen Flansch 22 übergeht und senkrecht zur Zentrumsachse des Ausgussstutzens 2 verläuft. Dieser äusserste Bereich des endständigen Flansches 22 bildet eine ringförmige Schweissfläche 27. Bevorzugterweise ist die zum Schlauchbeutel zu liegen kommende Seite der Schweissfläche 27 mit Energieleitelementen 28 versehen. Solche Energieleitelemente sind je nach Schweissverfahren jedoch nicht zwingend erforderlich. Auch die Anzahl und Grösse dieser Energieleitelemente können variieren und in der Form unterschiedlich gestaltet sein. Diese werden insbesondere benötigt, wenn die Schweissung mittels Ultraschall erfolgt.With reference to the FIGS. 1, 2 and 4 will now describe the spout in detail. This has a cylindrical jacket wall, which forms the actual spout and by an internal thread 21 is arranged. To increase the grip, the cylindrical shell wall is provided on the outside with a ribbing. At the lower end, a conically outwardly extending retaining wall region 24 adjoins the cylindrical jacket wall, which then merges into the actual terminal flange 22 and runs perpendicular to the center axis of the pouring spout 2. This outermost region of the terminal flange 22 forms an annular welding surface 27. Preferably, the side of the welding surface 27 coming to the tubular bag is provided with energy-conducting elements 28. However, such energy-guiding elements are not absolutely necessary depending on the welding process. Also, the number and size of these Energieleitelemente may vary and be designed differently in shape. These are especially needed when the welding is done by means of ultrasound.

Der auf der Aussenseite erkennbare Stützwandbereich 24 bildet ein Teil eines doppelwandigen Bereiches, der in der Figur 4 deutlich kennbar ist. Der innen liegende Anteil des doppelwandigen Bereiches wird durch eine konzentrisch zur Stützwand 24 verlaufenden Dichtschürze gebildet. Diese Dichtschürze ist jedoch statt nach aussen leicht nach innen geneigt verlaufend. Zwischen der Stützwand 24 und der Dichtschürze verbleibt eine ringförmige Kammer 29.The recognizable on the outside support wall portion 24 forms part of a double-walled area, which in the FIG. 4 clearly recognizable. The internal part of the double-walled area is formed by a concentric with the support wall 24 extending sealing skirt. However, this skirt is instead of outwardly inclined slightly inclined inwards. Between the support wall 24 and the sealing skirt remains an annular chamber 29th

Im oberen Bereich weist die zylindrische Mantelwand eine Erweiterung 200 auf. Diese Erweiterung 200 kann wie hier in der Figur 4 dargestellt stufenförmig gestaltet sein oder wie in der Figur 1 dargestellt, konisch ausgebildet sein.In the upper area, the cylindrical jacket wall has an extension 200. This extension 200 can be like here in the FIG. 4 be shown stepped or as in the FIG. 1 shown conical.

In den Ausgussstutzen 2 lässt sich ein Adapter 3 einschrauben. Dieser Adapter 3 ist rohrförmig gestaltet. Ein in der Einbaulage in den Ausgussstutzen hinein schraubbarer Teil bildet das Einlassende während das ausserhalb des Ausgussstutzen, zu liegen kommende Teil das Auslassende 31 bildet. Sowohl der Aussendurchmesser als auch der Innendurchmesser des Einlassendes ist grösser als die entsprechenden Durchmesser des Auslassendes 31. Das Einlassende ist mit einem Aussengewinde 32 versehen. Das untere Ende des Einlassendes ist mit einer unteren planen Endfläche 33 versehen. An dieser und mit dessen zylindrischen Rohrwand fluchtend ist mindestens ein kombinierter Perforier- und Schneidzahn 34 angeformt. Wie dies in den Figuren 1 und 2 ersichtlich ist, können selbstverständlich auch mehr als nur ein Perforier- und Schneidzahn vorhanden sein. Im hier dargestellten Beispiel sind immer zwei kombinierte Perforier- und Schneidzähne vorhanden. Da die Schnittebene in der Figur 4 so gelegt ist, dass diese genau zwischen den beiden Zähnen verläuft ist lediglich ein kombinierter Perforier- und Schneidzahn ersichtlich. Prinzipiell und dies ist aber für die vorliegende Erfindung nicht von Bedeutung kommen auch andere Zahngestaltungen in Frage und insbesondere können auch Perforierzahn und Schneidzahn getrennte unterschiedlich gestaltete Formen haben.In the spout 2, an adapter 3 can be screwed. This adapter 3 is tubular. A part which can be screwed into the pouring spout in the installed position forms the inlet end while the part coming to rest outside the spout nozzle forms the outlet end 31. Both the outer diameter and the inner diameter of the inlet end is greater than the corresponding diameter of the outlet end 31. The inlet end is provided with an external thread 32. The lower end of the inlet end is provided with a lower planar end surface 33. At this and with the cylindrical tube wall aligned at least one combined perforating and cutting tooth 34 is formed. Like this in the Figures 1 and 2 it can be seen, of course, more than just a perforating and cutting tooth can be present. In the example shown here, there are always two combined perforators and cutting teeth present. Since the cutting plane in the FIG. 4 is placed so that it runs exactly between the two teeth only a combined perforating and cutting tooth is visible. In principle, and this is of no importance for the present invention, other designs of teeth come into question, and in particular perforating tooth and cutting tooth can have separate differently shaped forms.

Das Auslassende 31 weist auf der Aussenfläche einen konischen Anzug auf und bildet so einen Schlauchaufsatz 35. Zwischen dem Auslassende 31 und dem Einlassende ist ein Dichtkragen 36 angeformt. Dieser Dichtkragen 36 bildet eine Sekundärdichtung zusammen mit der erwähnten Erweiterung 200. Die Erweiterung 200 und der Dichtkragen 36 sind entsprechend formlich aufeinander abgestimmt. Im hier dargestellten Beispiel ist der Dichtkragen 36 als radial nach aussen gerichteter Ring gestaltet, doch ist es auch möglich diesen Bereich konisch zu gestalten, was dann selbstverständlich zwingend nach sich zieht, dass auch die Erweiterung 200 gegengleich konisch gestaltet sein muss.The outlet end 31 has on the outer surface of a conical suit and thus forms a hose attachment 35. Between the outlet end 31 and the inlet end, a sealing collar 36 is formed. This sealing collar 36 forms a secondary seal together with the aforementioned extension 200. The extension 200 and the sealing collar 36 are correspondingly adapted to one another in terms of form. In the example shown here, the sealing collar 36 is designed as a radially outwardly directed ring, but it is also possible to make this area conical, which then inevitably inevitably entails that the extension 200 must be designed opposite conical.

Je nach Grösse und der Dicke der Folie des Schlauchbeutels lässt sich der Adapter 3 von Hand vollständig in den Ausguss 2 einschrauben. Da aber sowohl das Auslassende 31 als auch der Dichtkragen 36 eine glatte Oberfläche aufweisen lässt sich kaum eine relevante Kraft ausüben. Bei grösseren Schlauchbeuteln ist aber die Wandstärke beziehungsweise die Dicke der Folie aus der der Schlauchbeutel gefertigt ist so gross, dass dies kaum möglich ist. Hier wird der Adapter 3 vorerst in das Innengewinde 21 der zylindrischen Mantelwand eingeschraubt bis der kombinierte Perforier- und Schneidzahn 34 auf der Folie aufliegt.Depending on the size and the thickness of the film of the tubular bag, the adapter 3 can be screwed by hand completely into the spout 2. However, since both the outlet end 31 and the sealing collar 36 have a smooth surface, hardly any relevant force can be exerted. For larger ones Tubular bags but the wall thickness or the thickness of the film from which the tubular bag is made is so large that this is hardly possible. Here, the adapter 3 is initially screwed into the internal thread 21 of the cylindrical shell wall until the combined perforating and cutting tooth 34 rests on the film.

Wie in den Figuren 1 und 6 deutlich erkennbar sind am Einlassende plane Angriffsflächen 37 angeformt, die einander diametral gegenüber liegen, so dass der Stutzen mittels einem Werkzeug, beispielsweise einem Gabelschlüssel gefasst und weiter eingeschraubt werden kann, wobei nun die entsprechenden Folien geschnitten werden. Dank der relativ grossen und konisch nach innen gerichteten dünnwandigen Dichtschürze vermag diese auch in den planen Angriffsflächen 37 zu dichten. Dies wird zudem noch unterstützt durch den gegebenenfalls auch der Inhalt auf der Aussenseite der Dichtschürze anliegt und somit eine zusätzliche Dichtkraft ausübt. Insbeosndere wenn der Adapter vollständig eingeschraubt ist und Material aus dem Schlauchbeutel 4 gepresst wird, tritt diese zusätzliche Dichtfunktion ein. Während der Entleerung durch eine Pumpe wird oftmals auch eine Abgabe durch einen Pressdruck auf den Schlauchbeutel 4 bewirkt.As in the FIGS. 1 and 6 clearly visible at the inlet end plane attack surfaces 37 are formed, which are diametrically opposed to each other, so that the neck can be taken by means of a tool, such as a wrench and further screwed, now the corresponding films are cut. Thanks to the relatively large and conically inwardly directed thin-walled sealing skirt, it is also able to seal in the planar attack surfaces 37. This is also supported by the possibly also the content rests on the outside of the sealing skirt and thus exerts an additional sealing force. Insbeosndere when the adapter is completely screwed in and material is pressed out of the tubular bag 4, this additional sealing function occurs. During emptying by a pump, a discharge is often caused by a pressing pressure on the tubular bag 4.

Auf den Adapter 3 kann während der Benutzung der Einrichtung 1 auch immer ungewollt ein Drehmoment wirken. Dieses Drehmoment kann beispielsweise dann auftreten, wenn ein Anschlussschlauch 5 (siehe Figur 6) auf den Schlauchaufsatz 35 befestigt wird. Auch beim Aufsetzen des Anschlussschlauches 5 auf einem Gegenstück, beispielsweise an einer Pumpe oder an einer Dosiervorrichtung kann über dem Anschlussschlauch ein Drehmoment übertragen werden. Um zu vermeiden, dass dabei der Adapter 3 gelockert oder sogar soweit aus dem Ausgussstutzen 2 hinausgeschraubt wird, dass keine dichtende Verbindung mehr besteht, wird bevorzugterweise vorgeschlagen ein entsprechendes Sicherungsmittel vorzusehen. Dieses Sicherungsmittel ist am deutlichsten in der Figur 3 erkennbar. Bei dieser perspektivischen Teilansicht erkennt man eine an der Erweiterung 200 nach innen ragende Rastnocken 201. Entsprechend ist am Dichtkragen 36 eine Einrastausnehmung 38 eingeformt. Beim vollständigen Einschrauben des Adapters 3 in den Ausgussstutzen 2 kommt der Rastnocken 201 in die Einraustausnehmung 38 am Dichtkragen 36 zum Einrasten. Selbstverständlich lässt sich diese, Sicherung im einfachsten Fall auch umgekehrt gestalten, indem die Erweiterung 200 eine entsprechende Einrastausnehmung aufweist und dafür am Dichtkragen 36 ein entsprechend gegengleicher Rastnocken anformen. Auch anderweitige, durchaus gängige Lösungen zur Bildung einer solchen Verdrehsicherung lassen sich realisieren.On the adapter 3 can also act unintentionally during use of the device 1 torque. This Torque can occur, for example, when a connection hose 5 (see FIG. 6 ) is attached to the hose attachment 35. Even when placing the connection hose 5 on a counterpart, for example on a pump or on a metering device, a torque can be transmitted via the connecting hose. In order to avoid that while the adapter 3 is loosened or even as far out of the spout 2 is screwed out that no sealing connection exists, it is preferably proposed to provide a corresponding securing means. This securing agent is most evident in the FIG. 3 recognizable. In this partial perspective view one recognizes an extension 200 inwardly projecting locking cam 201. Accordingly, a Einrastausnehmung 38 is formed on the sealing collar 36. When fully screwing the adapter 3 in the spout 2 of the locking cam 201 comes into the Einraustausnehmung 38 on the sealing collar 36 for locking. Of course, these, fuse in the simplest case can be reversed by the extension 200 has a corresponding Einrastausnehmung and for molding on the sealing collar 36 a corresponding gegengleicher locking cams. Also other, quite common solutions for forming such a rotation can be realized.

Normalerweise wird zusammen mit dem Behältnis beziehungsweise dem Schlauchbeutel 4 der Adapter 3 als gesondertes Teil separat und steril verpackt mitgeliefert. In derselben sterilen oder aseptischen Verpackung lässt sich zudem auch ein Anschlussschlauch 5, gegebenenfalls bereits aufgesetzt wie in der Figur 6 gezeigt, mitliefern.Normally, together with the container or the tubular bag 4, the adapter 3 is supplied separately and packaged as a separate separate item. In the same sterile or aseptic packaging can also be a connection hose 5, possibly already placed as in the FIG. 6 shown, deliver.

Der Ausgussstutzen 2, der auf dem Behältnis 4 bereits angebracht ist, kann zusätzlich wie dies die Figur 5 zeigt, mit einer Abdeckung versehen sein. Prinzipiell könnte dies ein eingeschraubter Stopfen sein, der nach der Entfernung fortgeworfen wird. Dies wäre aber eine unnötig teure Variante, die auch kaum sinnvoll ist. Der Schlauchbeutel 4 ist, wie bereits erwähnt aseptisch verschlossen und die Folie des Schlauchbeutels ist genügend stark, dass hier nicht eine Zerstörung der Folie im Bereiche des Ausgussstutzens 2 erfolgt. Entsprechend könnte der Ausgussstutzen 2 auch vollständig offen bleiben. Bevorzugterweise wird jedoch vorgeschlagen den Ausgussstutzen 2 mit einer abziehbaren Folie zu verschliessen. Dies kann beispielsweise eine Aluminiumfolie sein, die mittels Peellack aufgeklebt ist. Eine solche abziehbare Folienabdeckung 40 ist in der Figur 5 dargestellt. Sie hat die Form einer Rondelle mit einer Abziehlasche 41. Die Klebverbindung der abziehbaren Folienabdeckung 40 mit dem Ausgussstutzen erfolgt auf der Stirnfläche der Erweiterung 200. Statt einer Verbindung der Folienabdeckung 40 mit der Erweiterung 200 mittels einem Peelinglack kann dies selbstverständlich auch mittels einer thermischen Schweissung erfolgen. Die Folienabdeckung 40 garantiert, dass keine Verunreinigung im Innenbereich, der von der zylindrischen Mantelwand des Ausgussstutzens 2 begrenzt wird, erfolgen kann.The spout 2, which is already mounted on the container 4, can also like this FIG. 5 shows, be provided with a cover. In principle, this could be a screwed plug that is thrown away after removal. But this would be an unnecessarily expensive option, which makes little sense. The tubular bag 4 is, as already mentioned aseptically sealed and the film of the tubular bag is strong enough that there is no destruction of the film in the areas of the spout 2. Accordingly, the spout 2 could also remain completely open. Preferably, however, it is proposed to close the spout 2 with a peelable film. This may be, for example, an aluminum foil, which is glued by means of peel-lacquer. Such a peelable film cover 40 is in the FIG. 5 shown. It has the form of a Rondelle with a Abziehlasche 41. The adhesive bond of the peelable film cover 40 with the spout is on the end face of the extension 200. Instead of a compound of the film cover 40 with the extension 200 by means of a Peeling lacquer can of course also be done by means of thermal welding. The film cover 40 ensures that no contamination in the interior, which is bounded by the cylindrical shell wall of the spout 2, can take place.
